摘要
建立了多刚体和刚柔耦合车辆系统动力学模型,对比研究了考虑车体弹性振动与否对车辆系统动力学性能的影响。结果表明,考虑车体弹性振动后,低速车辆的动力学性能变化较小,而高速车辆的动力学性能变化较大,且主要体现在旅客乘坐舒适度方面。此外,为了降低高速车辆车体弹性振动,还进行了转向架悬挂参数的优化匹配研究。结果表明,优选一系、二系垂向阻尼和减小抗蛇行减振器安装角度都可以降低车体弹性振动。
The dynamics models of multi-rigidbody and rigid-flexible coupling vehicle systems are set up.The effects whether the flexible vibration of the carbody is considered on the dynamics performance of the vehicle system are compared and researched.The result shows that,after consideration of the flexible vibration of the carbody,the change of dynamics performance of vehicles with low speed is fairly small,but the change of dynamics performance of vehicles with high speed is fairly big,and they are mainly reflected in the ride comfort of passengers.Furthermore,in order to reduce the flexible vibration of carbodies of high speed vehicles,the optimized matching of suspension parameters of bogies is researched.The result shows that,the flexible vibration of carbodies can be reduced by optimizing the primary,secondary vertical damping and reducing the installation angle of the anti-hunting damper.
